Since then, tremendous advances have been made in the treatment of NSCLC based on this discovery. Some of these studies have led to seismic changes in the concept of oncology research and spurred treatment advances beyond NSCLC, leading to a current true era of precision oncology for all solid tumors. We now routinely molecularly profile all tumor types and even plasma samples of patients with NSCLC for multiple actionable driver mutations, independent of patient clinical characteristics nor is profiling limited to the advanced incurable stage. We are increasingly monitoring treatment responses and detecting resistance to targeted therapy by using plasma genotyping. Furthermore, we are now profiling early-stage NSCLC for appropriate adjuvant targeted treatment leading to an eventual potential “cure” in early-stage EGFR+ NSCLC which have societal implication on implementing lung cancer screening in never-smokers as most EGFR+ NSCLC patients are never-smokers. All these advances were unfathomable in 2004 when the five papers that described “discoveries” of activating EGFR mutations (del19, L858R, exon 20 insertions, and “uncommon” mutations) were published. To commemorate this 20th anniversary, we assembled a global panel of thoracic medical oncology experts to select the top 20 papers (publications or congress presentation) from the 20 years since this seminal discovery with December 31, 2023 as the cutoff date for inclusion of papers to be voted on. Papers ranked 21 to 30 were considered “honorable mention” and also annotated. Our objective is that these 30 papers with their annotations about their impact and even all the ranked papers will serve as “syllabus” for the education of future thoracic oncology trainees. Finally, we mentioned potential practice-changing clinical trials to be reported. One of them, LAURA was published online on June 2, 2024 was not included in the list of papers to be voted on but will surely be highly ranked if this consensus survery is performed again on the 25th anniversay of the discovery EGFR mutations (i.e. top 25 papers on the 25 years since the discovery of activating EGFR mutations).Keywords: EGFR mutations, expert panel, top 20 papers, 20th anniversary, NSCLC

Cancer patients appear to be more likely to be diagnosed with coronavirus disease 2019 (COVID-19). This is supported by the understanding of immunometabolic pathways that intersect patients with infection and cancer. However, data derived by case series and retrospective studies do not offer a coherent interpretation, since data from China suggest an increased risk of COVID-19, while data from the United States and Italy show a prevalence of COVID-19 in cancer patients comparable with the general population. Noteworthy, cancer and COVID-19 exploit distinct patterns of macrophage activation that promote disease progression in the most severe forms. In particular, the alternative activation of M2-polarized macrophages plays a crucial role in cancer progression. In contrast, the macrophage-activation syndrome appears as the source of M1-related cytokine storm in severe COVID-19 disease, thus indicating macrophages as a source of distinct inflammatory states in the two diseases, nonetheless as a common therapeutic target. New evidence indicates that NAMPT/NAD metabolism can direct both innate immune cell effector functions and the homeostatic robustness, in both cancer and infection. Moreover, a bidirectional relationship exists between the metabolism of NAD and the protective role that angiotensin converting enzyme 2, the COVID-19 receptor, can play against hyperinflammation. Within this immunometabolic framework, the review considers possible interference mechanisms that viral infections and tumors elicit on therapies and provides an overview for the management of patients with cancer affected by COVID-19, particularly for the balance of risk and benefit when planning normally routine cancer treatments and follow-up appointments.

Background: The correlation between ALK gene copy number gain (ALK-CNG) and prognosis in the context of advanced non-small-cell lung cancer (NSCLC) remains a controversial issue. This study aimed to evaluate the association among ALK-CNG according to Fluorescent In Situ Hybridization (FISH), clinical characteristics and survival in resectable and advanced NSCLC.Methods: Clinical and pathological data of patients with resectable and advanced NSCLC were retrospectively collected. Tumor tissues were analyzed for ALK-CNG by FISH, and patients were divided in 3 groups/patterns on the basis of ALK signals: disomic [Pattern A], 3-7 signals [Pattern B], >7 signals [Pattern C]. The association between clinical and pathological features and ALK-CNG patterns was evaluated. Disease/progression-free and overall survival (DFS/PFS and OS) were estimated using the Kaplan-Meyer method.Results: A number of 128 (76.6 %) out of the 167 eligible patients were evaluable for ALK-CNG, displaying pattern A, B and C in 71 (42.5 %), 42 (25.1 %) and 15 (9 %) patients, respectively. Gains in ALK-CNG appear to be more frequent in smokers/former smokers than in non-smokers (74.2 % versus 20.4 %, respectively, p = 0.03). Pattern A and C seem more frequently associated with higher T-stage (T3-4), while pattern B appears more represented in lower T-stage (T 1-2) (p = 0.06). No significant differences in survival rate were observed among the above groups.Conclusions: A high ALK-CNG pattern might be associated with smoking status and theoretically it might mirror genomic instability. The implications for prognosis should be prospectively investigated and validated in larger patients' series.Trial Registration: We confirm that all the study was performed in accordance with relevant guidelines and regulations and that all the protocol (part of a larger project MFAG 2013 N.14282) was approved by the local Ethics Committee of the Azienda Ospedaliera Universitaria Integrata of Verona on November 11st, 2014.

Goals Of the Work: Osteonecrosis of the jaw (ONJ) is a severe complication of bisphosphonates treatment. Bisphosphonates reduce skeletal adverse events and give a clinical benefit to cancer patients. Therefore, it is necessary to identify appropriate procedures to reduce ONJ injures by using a successful monitoring program. In a retrospective study we analyzed the impact of a prevention program based on clinical oral cavity examination, dentists, and patients' education. The aim of the study was to evaluate if this approach might improve ONJ outcome in patients receiving pamidronate or zoledronate.Materials and Methods: We analyzed retrospectively two different groups of patients treated at our Institution: patients treated from October 2003 to June 2005 (group A) and patients treated from June 2005 to April 2007 (group B). In June 2005 the prevention program started for all our patients.Main Results: One hundred and eighty-six cancer patients with bone involvement, treated with bisphosphonates, were considered. Sixteen of them developed ONJ: eight before and eight after June 2005. We observed a consistent difference in the evolution of the two groups. In the first group, four patients underwent a major surgery (one partial maxillectomy, complicated by septic shock and oronasal communication; two partial mandibulectomies; and one segmental mandibular resection), with an important impairment of their quality of life; while the eight new ONJ cases, diagnosed after June 2005, were successfully treated without aggressive dental interventions, and achieved a good control of symptoms.Conclusions: Bisphosphonates-related ONJ is a frequent adverse event (8.6%). The monitoring program proved very efficient to improve the clinical outcome of ONJ, avoiding an aggressive treatment and using a conservative approach and medical therapy. [ABSTRACT FROM AUTHOR]

Massimo Broggini,1 Marina Chiara Garassino,2 Giovanna Damia11Laboratory of Molecular Pharmacology, Istituto di Ricerche Farmacologiche "Mario Negri", 2Division of Medical Oncology, Fondazione IRCCS National Cancer Institute, Milan, ItalyAbstract: Tivantinib is a selective, oral, non-ATP-competitive, small molecule inhibitor of the c-Met receptor, tyrosine kinase, which is implicated at different levels of tumor cell migration, invasion, proliferation, and metastasis. Tivantinib has shown antitumor activity in various human tumor cell lines and in xenograft models of human cancers, including non-small-cell lung cancer. Few therapeutic options are available at present for advanced non-small-cell lung cancer, so there is a pressing need for new therapeutic strategies to improve response and survival. Amplification of Met has been reported in more than 20% of lung tumors that have acquired resistance to epidermal growth factor receptor inhibitors, implying that treatment of these tumors with a c-Met inhibitor should overcome resistance. Tivantinib has shown interesting and promising results in advanced non-small-cell lung cancer and appears to be well tolerated, either alone or in combination with other drugs. An interesting additional feature is the ability of the drug to delay development of new metastasis, in agreement with the proposed role of Met in this particular setting.Keywords: non-small-cell lung cancer, Met inhibitors, tivantinib, biomarkers
